Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a pallet for loading a cylindrical article having a large load such as a food packaging material film and roll paper, and more particularly to a pallet for loading a sheet roll.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there is a wooden pallet for loading rolls, and in this conventional wooden pallet, another member is fixed to the surface of a flat pallet in order to stabilize the load.
[0003]
[Problems to be solved by the invention]
However, in the case of a conventional wooden pallet in which another member is fixed to the surface of a flat pallet, when the load is a film roll such as a food packaging material, it is difficult to make the load receiving portion cylindrical because the pallet is made of wood. In this case, there is a problem that an uneven load acts on the pallet contact portion and the film becomes white. As a countermeasure, a cushioning material such as a rubber material is conventionally attached, but in this case, the cost increases and there is a problem in terms of sanitation.
[0004]
Conventionally, there is also an injection-made pallet using a foamed resin. However, the pallet has a low strength, and is easily damaged and costly when pierced by a forklift claw at the time of carrying a load.
[0005]
Further, the conventional loading pallets do not have a reliable means for storing the pallets in an orderly state when the sheet rolls are not loaded, that is, when the pallets are empty.
[0006]
SUMMARY OF THE INVENTION An object of the present invention is to provide a sheet roll stacking pallet capable of solving the above-mentioned problems of the conventional technology.
[0007]
[Means for Solving the Problems]
The sheet roll stacking pallet according to the present invention has a load receiving portion having a load receiving portion surface having a concave shape substantially corresponding to the outer peripheral surface of the sheet roll to be loaded on the upper surface, and for supporting the load receiving portion. A plurality of post portions are provided so as to extend from the surface of the load receiving portion to the bottom surface, and the surface of the load receiving portion is partially concave at a position corresponding to each of the post portions, A convex rib is provided on at least both sides of the upper surface, and a concave shape is provided on the bottom surface at a position corresponding to the convex rib and can be fitted to the convex rib. Are provided, and are integrally hollow-molded with a resin material.

FIG. 1 is a plan view of a pallet for stacking sheet rolls according to an embodiment of the present invention, FIG. 2 is a front view of the pallet of FIG. 1, and FIG. 3 is a side view of the pallet of FIG. 4, FIG. 4 is a bottom view of the pallet of FIG. 1, FIG. 5 is a sectional view taken along line AA of FIG. 1, FIG. 6 is a sectional view taken along line BB of FIG. FIG. 2 is a sectional view taken along line CC of FIG.
[0010]
As shown in these drawings, the sheet roll stacking pallet 10 of this embodiment of the present invention is provided with the side legs 11A and the center leg 11B on the bottom side, and substantially on the outer peripheral surface of the sheet roll to be stacked. The load receiving portion having the load receiving portion surface 12 having the matching concave shape is provided on the upper surface side, and is integrally formed by hollow molding with a resin material such as high-density polyethylene. As shown in FIG. 1, FIG. 4, FIG. 6, and FIG. 7, the pallet 10 of this embodiment includes a plurality of pallets 10 arranged in a matrix so as to support a receiving portion having a receiving portion surface 12. In this embodiment, twenty post portions 13A, 13B and 14A are provided so as to extend between the load receiving portion surface 12 and the bottom surface side.
[0011]
As best shown in FIGS. 1 and 6, the post portion at the center portion is composed of a post portion 13A extending from the upper surface side and a post portion 13B extending from the bottom surface side. It is open at the bottom of the concave elongated recess 12B partially formed at the center. As shown in FIG. 6, the post portion 13A and the post portion 13B are connected to each other at a substantially intermediate portion between the upper surface and the bottom surface.
[0012]
On the other hand, the post portions 14A distributed on both sides of the central portion are formed so as to extend from the bottom surface side to the upper surface side, as shown in FIGS. Is formed at a position depressed from the general surface of the load receiving portion surface 12, so that the load receiving portion surface 12 has a concave portion 12A having a concave shape at a position corresponding to each of the post portions 14A. If the elongated recess 12B and the recess 12A as described above are not formed on the surface 12 of the load receiving portion where the post is located, the top of the post is directly located on the surface 12 of the load receiving portion. Then, when the film sheet roll is stacked on the load receiving surface 12, the load causes the top of the post to slightly protrude from the surface of the load receiving portion without the post. In this case, the sheet portion of the sheet roll that is in contact with the protruding post portion receives a large stress for a long period during storage and becomes white. The width and depth of the concave portion 12A are preferably set to such a degree as to prevent the protrusion of the post portion which causes such a problem of whitening when the sheet roll is stacked. In addition, the width and depth of the elongated concave portion 12B are determined in consideration of the amount of molding resin involved in the molding of the center leg, while preventing the protrusion of the post portion that causes such a whitening problem when the sheet roll is stacked. It is preferable that the amount of the resin in that portion is not reduced.
[0013]
In the pallet 10 of this embodiment, as shown in FIGS. 1, 2, 5 and 6, convex ribs 15 having convex shapes are provided on both sides of the upper surface. As shown in FIGS. 4 and 6, a concave rib 16 having a concave shape is provided on the bottom surface at a position corresponding to the convex rib 15 on the upper surface side so as to be fitted to the convex rib 15. Have been.
[0014]
Further, in the pallet 10 of this embodiment, as shown in FIG. 2 and FIG. 4, near the four corners on the bottom side, rope hanging portions 17 for fixing and holding the sheet rolls to be stacked are formed. I have.
[0015]
Next, a method of using the sheet roll stacking pallet 10 having such a structure will be briefly described with reference to FIGS. 8 and 9. First, FIG. 8 shows a state in which a sheet roll 1 such as a food packaging material film or roll paper is placed on a load receiving surface 12 of a load receiving support of a pallet 10, and two ropes 2 hung on a rope hook 17. The state fixed and held by is schematically shown in a perspective view. In this state, the sheet roll 1 can be stably stored in an appropriate storage place such as a warehouse. When it is desired to transport from a storage location to another location, for example, a claw of a forklift is inserted into the space between the side leg 11A and the central leg 11B of the pallet 10 and lifted. Thus, the sheet roll 1 can be easily conveyed while being loaded thereon.
[0016]
FIG. 9 is a cross-sectional view illustrating a state in which pallets 10 are stacked and stored when a so-called empty pallet is not loaded with sheet rolls. As shown in FIG. 9, when the pallet 10 of this embodiment is not used, the convex ribs 15 on the upper surface of the lowermost pallet 10 are fitted into the corresponding concave ribs 16 on the bottom surface of another pallet 10 when not in use. Thus, another pallet 10 is stacked. Similarly, another pallet 10 can be stacked on the other pallet 10. In this way, unused pallets 10 can be stored in an orderly manner.
[0017]
【The invention's effect】
The pallet of the present invention has a load receiving portion formed into a cylindrical shape by hollow molding so that a load such as a sheet roll can be fixed stably, and has a built-in post portion for supporting a heavy load, and a surface of the load receiving portion hitting the post portion. By forming a partially concave shape, the load can be dispersed and uniform load distribution can be achieved, thereby preventing whitening of the film of the loaded sheet roll.
[0018]
Since the pallet of the present invention is integrally hollow-molded with a resin material, the pallet is also excellent in hygiene, and if high-density polyethylene or the like is used as the resin material, sufficient strength can be ensured.
[0019]
Further, since the pallet of the present invention is formed by hollow molding, the cost of the mold is lower than that of injection molding, and post-processing after molding is almost unnecessary, so that the product is inexpensive.
[0020]
Still further, empty pallets can be stacked and stored in an orderly manner, and distribution costs can be reduced.
